Personality characteristics and bariatric surgery outcomes: a systematic review
Trends in psychiatry and psychotherapy
Numerous studies have focused on psychological assessment of bariatric surgery candidates, aiming to identify which psychological variables, including personality characteristics, are related to successful surgical prognosis. To analyze, by means of a systematic literature review, longitudinal studies that investigated personality traits and disorders as possible predictors of outcomes in bariatric surgery. PsycInfo, PubMed, and Scopus databases were searched for studies published between 2005 and 2015, using the keywords "bariatric" AND "personality." Quantitative longitudinal studies in English, Portuguese, or Spanish were selected for review if they assessed personality as an outcome predictor of BS in people aged 18 years or older. Sixteen articles were analyzed. The results of this review suggest that externalizing dysfunctions might be associated with less weight reduction, while internalizing dysfunctions appear to be associated with somatic concerns and p...
Personality assessment in morbid obesity
German J Psychiatry, 2002
Objective: To analyze the personality traits and psychological discomfort, eighteen months after bariatric surgery (vertical banded gastroplasty) in morbidly obese patients. Method: We used the Millon Clinical Multiaxial Inventory-II (MCMI-II) for assessing personality traits in 100 morbidly obese patients. Results: Six basic factor dimensions in the mental state were obtained: (1) Personality traits and Psychological Discomfort, (2) Histrionic-Narcissistic-Antisocial, (3) Neurotic, (4) Paranoid, (5) Alcohol dependence, and (6) Dependent. Conclusions: Our results suggest that people with morbid obesity after bariatric surgery share characteristics of personality disturbances and psychological discomfort, and that subtypes of different personality dimensions are associated with wide groups of psychopathological symptoms (

Objective: Bariatric surgery is an effective treatment for obesity, which has been increasing worldwide. However, bariatric surgery causes dramatic physical changes that can cause significant stress. Prior research has found that psychological variables such as personality traits and levels of psychopathology can influence success after bariatric surgery (in terms of body-mass index [BMI] reduction and weight loss). However, most prior studies have been limited by small sample sizes, inconsistent follow-up, and categorical assessment of psychopathology. Methods: The present study examines the predictive utility of the Personality Assessment Inventory (PAI) scales for three bariatric surgery outcomes (BMI reduction, weight loss, and percent excess weight loss [%EWL]) across ten follow-up points five years after surgery. It also examines the largest sample of bariatric surgery-completing patients (N = 2,267) on the PAI to date. Latent growth modeling was used to examine change in the ...
International Journal of Psychology and Psychological Therapy
AbstrAct Bariatric surgery has proven to be the most effective treatment for severe obesity. Weight loss and long-term maintenance depend on patient's ability to implement permanent lifestyle changes. Presurgical psychological evaluation and intervention are proposed for a better post surgical prognosis. The aim of present study was to make a psychosocial profile with the results of psychological evaluation performed to 129 bariatric surgery candidates and to determine associations between psychological variables with obesity level. Patients were evaluated with an oral interview, the MINI International Neuropsychiatric Interview, and the following self-reported instruments: Beck Depression Inventory, Anxiety Sensitivity Inventory, Stress Control Perception, Risk Factors related to Eating Behavior Disorders Scale, Quality of Life and Health Inventory. Study population was divided in groups according to obesity level, evaluation results were compared according to these groups. Res...
Type D personality and predictive factors of Body Mass Index in bariatric surgery candidates (eng)
Klinik psikiyatri dergisi, 2021
Bariatrik cerrahi adaylarında D Tipi kişilik ve vücut kitle indeksinin yordayıcı faktörleri SUMMARY Objective: This study aimed to investigate depressionanxiety levels, sexual lives, childhood traumatic experiences, self-esteem, eating attitudes, and Type D personality traits in bariatric surgery candidates. Method: Our study was conducted between June 2019 and December 2019 and included a total of 100 individuals, 50 bariatric surgery candidates and 50 healthy people. A sociodemographic data form, the Beck Depression Inventory, the Beck Anxiety Inventory, the Childhood Trauma Questionnaire, the Type D Personality Scale, the Arizona Sexual Experiences Scale, the Rosenberg Self-Esteem Scale, and the Eating Attitudes Test were used in our study. Results: The scores of Type D Personality, Arizona sexual experiences, childhood trauma, eating attitude, and self-esteem scales were significantly higher in the patient group than in the control group. There was no statistically significant difference between the anxiety and depression scores of both groups. In addition, it was found that the predictive factors of the Body Mass Index were education, self-esteem, eating attitude, and childhood traumas, explaining 63.5% of the variance. Type D personality, on the other hand, was not found to be one of the predictive factors. Discussion: Bariatric surgery candidates undergoe routine psychiatric examinations prior to their operations, and preoperative follow-up interviews with a psychiatrist is believed to be important for these individuals.
Personality Profiles of the Morbidly Obese after Vertical Banded Gastroplasty
Obesity Surgery, 2003
Background: The authors attempted to determine if mental status could predict personality profiles, 18 months after surgery in morbidly obese patients. Methods: Personality characteristics of 100 morbidly obese patients (85 female, 15 male) were analyzed after bariatric surgery (vertical banded gastroplasty). Patients were given the Millon Clinical Multiaxial Inventory-II (MCMI-II). Data were compared with a Spanish clinical population to validate the test in our country. Results: Significant differences were found in Schizoid scale (P<0.0001), Paranoid scale (P<0.001), Histrionic scale (P<0.0001), Compulsive scale (P<0.0001), and Delusional disorder scale (P<0.0001) between the two groups. When psychiatric comorbidity appeared, there were higher values on these scales. Conclusions: Morbidly obese patients undergoing bariatric surgery show traits and personality disturbances, and the mental state impairs the personality structure.

Objective : To examine the relationships between dysfunctional eating patterns, personality, anxiety and depression in morbidly obese patients accepted for bariatric surgery. Design : The study used cross-sectional data collected by running a randomized controlled trial (http://clinicaltrials.gov/ct2/show/NCT01403558). Subjects : A total of 102 patients (69 women, 33 men) with a mean (SD) age of 42.6 (9.8) years and a mean BMI of 43.5 (4.4) kg/m(2) participated. Measurements : Measurements included the NEO-PI-R (personality: neuroticism, extroversion, openness, conscientiousness and agreeableness), the TFEQ-R-21 (dysfunctional eating: emotional eating (EE), uncontrolled eating (UE) and cognitive restraint of eating (CR)) and the HADS (anxiety and depression). Results : The personality traits neuroticism and conscientiousness were more strongly correlated with dysfunctional eating than anxiety and depression. These differences were most pronounced for emotional and cognitive restrain...
Personality and Obese Body Mass Index
PsycEXTRA Dataset, 2000
This study investigated the relationship between obese range Body Mass Index (BMI) and personality variables as measured by the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). The sample consisted of 129 obese participants referred for preoperative psychological evaluation. Each completed an MMPI-2 and clinical interview. Multilevel linear regression analysis was used to assess the contribution of personality variables to the prediction of variance in obese range BMI. Age, Scale 9 (Hypomania), and Scale 4 (Psychopathic Deviate) emerged as statistically significant predictors of BMI. Each predicted 7.8%, 6.4%, and 3.1% of the variance of participant BMI, respectively, with a combined prediction power of 17.3%. F-scores for the final, best fit model, with age on Level 1 and Scale 9 and Scale 4 on Level 2, were statistically significant (p<.0009). Results suggest severely obese bariatric surgery candidates may be more prone to impulsivity, irritability, and instability. However, limited predictive power of MMPI-2 scales indicates restricted clinical utility.
Psychological Profile of Patients Eligible for Bariatric Surgery
ABCD. Arquivos Brasileiros de Cirurgia Digestiva (São Paulo), 2016
Background: The psychologist who works in bariatric surgery has a role to receive, evaluate, prepare and educate the patient who will undergo the surgical procedure. Psychological evaluation becomes important in so far as allows us to obtain data on personal and familiar history and allow tracing of possible psychopathology. Aim: To collect data on psychological evaluations of patients in a bariatric surgery service of a public hospital in order to describe the psychological profile of patients in this service. Method: Data were collected from 827 patients between 2001 and 2015, using data from an interview, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and Binge Eating Scale (BES). Results: The mean age of patients before surgery was 39 years+/- 10, the mean BMI was 51 kg/m²+7, and most patients (81%) were female. The average score on the BDI was 14.8+8 and women had significantly higher scores than men. On the BAI the average score was 11+8 and on the ECAP was 14+8...
